LILO & SAM: IN-FLIGHT FIGHT

Catching a 6:30 a.m. plane can make anyone cranky, but LINDSAY LOHAN and SAMANTHA “Tha’s a Man” RONSON started screaming at each other in the skyway lounge while waiting for their New York-LA flight – and even after boarding raged nonstop so loudly that half the plane heard them!

Things got weirder shortly into the flight when Lindsay called a flight attendant over, whimpering she’d “bumped her head” and needed ice for it. When the attendant asked how she’d hurt herself, LiLo looked at Sam with wounded eyes…and suddenly burst into tears! “I…I… got hurt before I came to the airport,” blubbered Lindsay.

Man-In-Charge Samantha abruptly cut in and told the attendant not to worry about Lindsay – she’d keep watching her for possible concussion. (Thanks, Dr. Ronson!) Shrugging, the attendant left the couple alone, and they girly-sniped nonstop in what seemed like meaningless arguments – and at one point, Lindsay was overheard whining to Sam in a childish voice: “You apologize to me…right now!”
